(M547) The master spirit of the expedition was now removed, and its operations were languid and undecided, for Nicias had no heart in it. The delays which occurred gave the Syracusans time to prepare, and more confidence in their means of defense. So that when the forces of the Athenians were landed in the great harbor, they found a powerful army ready to resist them. In spite of a victory which Nicias gained near Olympeion, the Syracusans were not dejected, and the Athenian fleet was obliged to seek winter quarters at Catana, and also send for additional re-enforcements. Nicias unwisely delayed, but his inexcusable apathy afforded the enemy leisure to enlarge their fortifications. The Syracusans constructed an entirely new wall around the inner and outer city, and which also extended across the whole space from the outer sea to the great harbor, so that it would be difficult for the Athenians, in the coming siege, to draw lines of circumvallation around the city. Syracuse also sent envoys to Corinth and Sparta for aid, while Alcibiades, filled now with intense hatred of Athens, encouraged the Lacedæmonians to send a force to the Sicilian capital. He admitted that it was the design of Athens first to conquer the Sicilian Greeks, and then the Italian Greeks; then to make an attempt on Carthage, and then, if that was successful, to bring together all the forces of the subjected States and attack the Peloponnesus itself, and create a great empire, of which Athens was to be the capital. Such an avowal was doubtless the aim of the ambitious Alcibiades when he first stimulated the enterprise, which, if successful, would have made him the most powerful man in Greece; but he was thwarted by his enemies at home, and so he turned all his energies against his native State. His address made a powerful effect on the Lacedæmonians, who, impelled by hatred and jealousy, now resolved to make use of the services of the traitor, and send an auxiliary force to Syracuse.
